Performance Of Cold Bituminous Emulsion Mixtures (Cbem\u27s) Incorporating Waste Material

ABSTRAK This paper presents brief design procedure and the performance of Cold Bituminous Emulsion Mixture (CBEM\u27s) incorporating waste material. Three design procedures were combined and adopted in this investigatiOn. One was based on the Asphalt Institute guidelines, two others were based on the AASHTO. The binder used was a Cationic Bitumen \u27Emulsion that contains 62 % residual bitumen of 100-pen grade base bitumen produced by TotalFinaElf Ltd.-UK. The aggregates were limestone coarse aggregate, red porphyry sand a by-product of stone crusher, and limestone filler. The results indicated that the Optimum Residual Bitumen Content was 6 %. Most properties tested meet the specification. However the Total Voids in medium compaction was 12.575 % that can be reduced by simply increasing the compactive effort to heavy compaction that gave 9.155 % which is within the allowable range. The strength of the mixture can be significantly increased by either adding or substituting the filler with 2 % Ordinary Portland Cement in order to be equal with hot mixes at full curing condition where all water content had evaporated. It can be concluded that by increasing compactive effort. the total voids can be reduced. Addition or substitution of filler with OPC gives significant strength improvement. However, the concern remains on weak early strength and long curing time. Therefore a lot of efforts are still need to be endeavored to improve the performance of CBEM\u27s.
